I am in the market for a new grinder for commercial use (up to 10kg in 7 hours on our busiest day). I am unhappy with the dose (by weight) consistency of the Robur E and am trying to find out if there is a better option out there.
I am interested in opinions on Robur E, Compak K10 Fresh, Anfim Super Caimano On Demand, Mahlkonig K30 Vario/Twin, BNZ MD74 with Doserless mod etc
Please only reply if you have actually used the grinder you are adding info about and please stick to the proposed format to make this resource useful and easy to navigate for future viewers.
Here goes:
Grinder: Mazzer Robur Electronic
Any Mods: Yes, custom static screen that mimics the original in shape, but using thinner wire. It is a square mesh readily available from bunning etc.
Grind Retention: 20-30g (estimated)
Time to grind x grams: Vaires depending on burr age, but around 4 sec / 20g.
Dose variance over 20 weighed shots post burr break in period: +/-1g
Conical/Flat Burr: Conical
Doses cleanly into center of portafilter (y/n): Yes, but can be messy due to clumping issues.
Clumping issues (y/n): Yes. Anti Static mesh compresses coffee and causes it to fall out in clumps.
Static Issues (y/n): No. But if you remove the anti static mesh then it sprays all over the place and has major issues.
Over heating Issues (y/n): No
Other comments: No suitable soltuion found to make this grinder more perfect. Anti static screen causes compression of the coffee in the exit chute and hence clumping and a weird drop. If you remove it the coffee sprays everywhere and it doesnt dose cleanly or consistently. The biggest problem however is that the dose (by weight) has a variance of up to 2g and this makes the "electronic" claim of the grinder mostly useless.
